I short circuited the 3V3, 5V0 and all four 12V lines in turn. The power supply did shut down, and once the short was removed and the unit switched off for at least one second, resumed normal operation. Although listed here at the beginning of the testing section, I tend to leave this test until the very end, in case it doesn't quite go to plan.

Total Power Supply Loading

748W

The DC voltage regulation of the Lian-Li Silent Force 750W is excellent. I was able to take the power supply to 100% of the rated load and the power supply held the rails well within the ATX12V specification, the primary 3V3, 5V0 and particularly the 12V rails are almost perfect.
